| |
| function new(string name = "my_obj") |
| super.new(name); |
| ... |
| endfunction |
| ... |
| endclass</pre></blockquote><p>However, in UVM 1.0 and UVM 1.1, the presence of such a constructor were not enforced by the library and they were technically optional. If no constructor was specified, a default constructor was provided by SystemVerilog:</p><blockquote><pre>class my_obj extends uvm_object; |
| ... |
| `uvm_object_utils(my_obj) |
| |
| function new(); |
| endfunction |
| ... |
| endclass</pre></blockquote><p>Note the important difference: in the default constructor, there is no <i>name</i> argument. Because the factory could not rely on the presence of that argument, <a href="../base/uvm_object-svh.html#uvm_object" class=LClass id=link99 onMouseOver="ShowTip(event, 'tt6', 'link99')" onMouseOut="HideTip('tt6')">uvm_object</a> instances were created by calling <i>new()</i> without any arguments and subsequently setting the object instance name using <a href="../base/uvm_object-svh.html#uvm_object.set_name" class=LMethod id=link100 onMouseOver="ShowTip(event, 'tt81', 'link100')" onMouseOut="HideTip('tt81')">uvm_object::set_name</a>.</p><blockquote><pre>obj = new(); |
| if (name != "") obj.set_name(name);</pre></blockquote><p>In most cases, this difference was not significant. However, for any class that makes use of the value of the <i>name</i> argument in the constructor,</p><blockquote><pre>class my_obj extends uvm_object; |
| your_obj sub; |
| |
| `uvm_object_utils(my_obj) |
| |
| function new(string name = "my_obj") |
| super.new(name); |
| sub = your_obj::type_id::create({name,".sub"}); |
| endfunction |
| ... |
| endclass</pre></blockquote><p>a difference in behavior was observed between instantiating an object directly:</p><blockquote><pre>my_obj o = new("o");</pre></blockquote><p>and instantiating an object via the factory:</p><blockquote><pre>my_obj o = my_obj::type_id::create("o");</pre></blockquote><p>The difference could have been worked around by overriding the <a href="../base/uvm_object-svh.html#uvm_object.set_name" class=LMethod id=link101 onMouseOver="ShowTip(event, 'tt81', 'link101')" onMouseOut="HideTip('tt81')">uvm_object::set_name</a> method to percolate the effect of the name change. However, that work-around was often impossible or too late. In the examples above, the former creates an instance of <i>your_obj</i> named “o.sub” whereas the latter creates an instance named “my_obj.sub”. It made it impossible to control the sub-object factory based on the parent object name.</p><p>Instantiating coverage group is another example where the work-around did not work. Coverage groups cannot be renamed and must be instantiated in the encapsulating object’s constructor. The following example would create coverage groups that are always named “my_obj” when using the object factory.</p><blockquote><pre>class my_obj extends uvm_object; |
| covergroup my_cg(string name); |
| option.name = name; |
| ... |
| endgroup |
| |
| `uvm_object_utils(my_obj) |
| |
| function new(string name = "my_obj") |
| super.new(name); |
| my_cg = new(name); |
| endfunction |
| ... |
| endclass</pre></blockquote><p>Because the object factory is such a fundamental element of UVM, it is important that it be able to rely on the presence of a <i>name</i> argument in object constructors.</p></div></div></div> |
